It's looking bleak. I didn't think Stadia had much promise, anyway. But there's little hope to turn it around.
Game ownership is interesting. There's basically a bunch of DRM. Physical games you don't fully own usually anyway in the last generation or so. And just because you buy a game on one platform doesn't mean you own it in perpetuity on all future platforms. It's a license you own to play the game on its particular platform.
